Sulfhydryl Compounds 48-53 serpin family A member 1 Homo sapiens 63-89 2002060-2 1991 Whereas native alpha 1-PI combines rapidly and quasi-irreversibly with neutrophil elastase, the thiol-modified alpha 1-PI derivatives are dissociable reversible competitive inhibitors of the enzyme, with values of Ki in the range of 6-7 nM. Sulfhydryl Compounds 96-101 serpin family A member 1 Homo sapiens 111-121 2002060-4 1991 Once native alpha 1-PI has combined with neutrophil elastase, the enzyme-inhibitor complex retains a reactive thiol group, but the two proteins can no longer be dissociated by subsequent reaction with ANM, even after exposure to sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Sulfhydryl Compounds 110-115 serpin family A member 1 Homo sapiens 12-22
